Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format lesson. 

Take a look at some molecules that are so cool, they're polar! Scholars examine the effect polarity has on a molecule's shape and charge. Change up the view and choose between an opaque or transparent molecular surface, complete with...

Protons and neutrons and electrons, oh my! Physical science scholars get hands-on with interactive atomic modeling. Starting with a simple helium atom, participants create and name ions, then build isotopes. Questions throughout the...

Teach your class to think of electrons as tiny packets of energy that travel in waves. Through a short video and diagram, participants see how electrons are located around the nucleus of an atom. They then get into groups and try to...

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, learners build molecules based on the chemical formulas of common compounds.

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

What makes helium so Noble, anyway? Explore the bonding properties of helium versus those of hydrogen using an interactive resource. Science scholars manipulate atoms of each element and observe changes in potential energy as the atoms...

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

An interesting lesson takes pupils on a trip through the carbon cycle. A reading passage allows scholars to take notes and make choices about what happens to the carbon on its journey. This third lesson in a series of 21 discusses...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Here is a six-page exploration that will spark interest in the periodic table of elements. After reading a diagram-supported explanation of the periodic table's organization, pupils answer questions to familiarize themselves with it. To...

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Certain materials do not always maintain the same physical properties when they exist in the nanoscale. Help your classes to explore this idea through an experimental lesson. Scholars use spectroscopy with samples of silver solution...

From molecules to nanotubes, an engaging unit explores the world of tiny science. Fifteen hands-on experiments and lessons engage young scientists as they learn chemistry. Discussions, worksheets, and data analysis reinforce the concepts...

Ready to introduce the realities of molecular geometry to chemistry pupils? Use a logic-based interactive! Perfect as individual practice, the puzzles explore the bond angles and repulsions present in three common molecular shapes.

Accommodate your chemistry class with an experiment that is both entertaining and educational. Through the activity, blossoming chemists perform calculations on various isotopes, as represented by beans and legumes, to obtain...

How can radioactive decay help date old objects? Learners explore half-life and radioactive decay by conducting an experiment using pennies to represent atoms. Young scientists graph data from the experiment to identify radioactive decay...

Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...
